Founded by Michael Dubrovsky & Diedrik Vermeulen
We live in a world where wearables track heart rate, sleep, and glucose 24/7, yet blood testing—the most critical health data source—is still:
🚫 Infrequent – Most people only test once per year at a doctor's visit.
🚫 Incomplete – Many key biomarkers are not tested until symptoms appear.
🚫 Inconvenient – Booking an appointment, traveling to a lab, and waiting weeks for results is a hassle.
🚫 Painful – Finger pricks and venous blood draws deter regular tracking.
🚫 Fragmented – No easy way to combine biomarker data with wearables or look at trends in past blood test data.
Meanwhile, people want more and better insights into their health, whether for longevity, athletic performance, metabolic health, hormonal balance, chronic disease prevention, or chronic disease management.
🔬 The team spent the last 2.5 years experimenting with at-home blood test kit offerings to solve this problem and tested tens of thousands of people.
With the SiPhox Health Ultimate Program, they brought blood biomarker tracking, painless home sample collection, advanced biomarkers, personalized insights, body composition, and wearable integration into one seamless platform—so you can take control of your health without paperwork, clinics, finger pricks, or expensive lab tests.

They launched their service in beta September of 2022 🚀

They have since served 10s of thousands of users. Here are their learnings:

Their team is made up of experts, Ph.D.s, MDs, and engineers, who are passionate about blood testing and health optimization. SiPhox is the only direct-to-consumer (DTC) home blood testing company developing its own hardware.
✅ More value for your money
They avoid costly partnerships with celebrities and focus on shipping new features as their main driver of growth.
6 out of 10 Americans have at least one chronic disease. Getting and staying healthy is more of a priority than ever before. Wearables, CGMs, and health tracking are becoming mainstream, but blood testing is stuck in the past—it’s inconvenient, painful, and limited to annual checkups.
SiPhox Health bridges the gap, combining at-home biomarker testing with a seamless, full-featured health dashboard.
SiPhox Health, backed by Khosla Ventures, Intel Capital, and Y Combinator, is a full-stack home blood testing company currently offering consumers and businesses mail-in test kits to conveniently measure a broad range of biomarkers. Founded at MIT, their mission is to commercialize SiPhox Home—a silicon photonic chip-based device that delivers instant blood test results at home, making biomarker testing easier, smarter, and more accessible than ever.
